This project examines how population health status is currently reflected in the national income accounts, the advantages and shortcomings of this approach, and potential alternatives that would more systematically capture the aggregate economic impact of changes in health status. This project considers how individual-based measures of health status valuation, such as quality-adjusted life years, can be used at the national level to develop a structure for augmenting aggregate measures of economic activity to reflect changes in the health of the population as a whole, as well as for particular geographic or demographic subsets of the economy and population.
